Q

When would NO TREATMENT be indicated for a root fracture?

A

If the coronal fragment is still in place.

monitor for spontaneous repositioning

20
Q

Following a root fracture, if the coronal fragment is mobile, what would the most suitable treatment option be?

A

XLA of the coronal fragment and allow the apical fragment to be displaced by natural exfoliation.

21
Q

What would be observed in an alveolar fracture?

A

Mobility and dislocation of a segment.

22
Q

How would you manage an alveolar fracture?

A
  1. Reposition under local/general anaesthetic.
  2. Splint and stabilise for 4 weeks.
23
Q

Following a concussion injury, what would be present orally?

A

Changes may not be visible.

Tender to touch but has not been displaced.

Normal mobility.

24
Q

What may be observed following a subluxation injury?

A

Similar to concussion, tender to touch but changes may not be visible.

  • GINGIVAL BLEEDING FROM THE GINGIVAL MARGIN*
25
What are luxation injuries?
Where the tooth has altered in position.
26
What are the 3 types of luxation?
1. Extrusive (pulled out) 2. Intrusive (pushed in) 3. Lateral (angulation)
27
What is an extrusive luxation?
Partial displacement of the tooth out of the socket.
28
Why is a intraoral PA a good diagnostic tool for an extrusive luxation?
Confirms extrusion as it may present similar to a root fracture.
29
If the there is no occlusal interference in an extrusive or lateral luxation, what would the best treatment option be?
Leave and allow to spontaneously reposition.
30
If there is some occlusal interference from the extrusive or lateral luxation, what is the best mode of treatment?
Extraction under LA.
31
What is a lateral luxation?
When the tooth has been displaced in a palatal/lingual or labial direction.
32
With regards to mobility, what would be expected in a lateral luxation?
Immobile due to the root impinging on the bone.
33
What happens in an intrusive luxation?
Displacement through the labial bone which can impinge on the developing successor.
34
What is the preferred method of treatment for an intrusive luxation?
Allow to spontaneously reposition for 6 months - 1 year.
35
What is the first thing to do after an avulsion?
Locate the missing tooth fragment.
36
Should primary teeth be re-implanted after avulsion?
No - NEVER reimplant primary teeth.
37
What are the intervals for follow up?
1. 2 weeks 2. 4 weeks 3. 3 months 4. 6 months 5. yearly to 5 years and beyond.
38
What does a Core Outcome Set do?
Tracks how the teeth are healing.
39
What 9 things are included in the Core Outcome Set?
1. PDL healing 2. Pulp Space Healing 3. Pain 4. Discolouration 5. Tooth Loss 6. Quality of Life 7. Aesthetics (pt perception) 8. Trauma Related Dental Anxiety 9. Number of Clinical Visits
40
At what ages do permanent incisors develop and calcify?
Between 0-3 years.
41
If trauma occurs during 0-3 years old, what could the effect of this be?
Damage on the permanent dentition.
42
What would a colour change of yellow indicate?
Pulp Canal Obliteration
43
What are the 2 different types of resorption patterns associated with tooth trauma?
1. Infection Related Inflammatory Root Resorption - root shortens; gets eaten away by the infection. - red shine through around the tooth. 2. Ankylosis Related Replacement Root Resorption - trauma site doesn’t grow down with the rest of the dentition.
44
Advice for Parent/Guardians:
1. There is a risk that the primary tooth may lose vitality and die. 2. The parent should look out for: - discolouration - swelling or lumps on the gum - mobility - tenderness / pain. 3. There is also risk of damage to the PERMANENT tooth.
45
How might tooth tenderness / pain be observed in a child?
A change in diet or refusal to bite on front teeth.
46
What are 8 possible complications to permanent teeth following primary tooth trauma?
1. Opacity 2. Hypoplasia 3. Dilaceration 4. Root angulation alteration 5. Arrest of root development - fully or partially. 6. Delayed eruption due to granulation tissue 7. Ectopic eruption (lost guidance pathway) 8. Impaction to malformation
